One of my favourite royal hat photos featuring a young girl during a June 2015 visit to China who couldn’t resist reaching out to explore Queen Mathilde’s headpiece- one I think might be her largest flower. Hat by Fabienne Delvigne; photo by Philip Reynaers/Photo News S.A. via Corbis

I find that I like many of these hats where the flower, though much larger than life, is a part of a carefully planned set of embellishments (leaves, net, feathers, etc), but the ones that look like the wearer just plopped a big flower onto her head, not so much.

There are indeed, some huge Philip Treacy blooms on Sophie above! While Treacy’s designs are legendary, Sophie has hit a spectacular millinery stride with Jane Taylor. I think these are her Jane Taylor hats with biggest flowers
